hello everybody, i need some help/advice, my boxer is 26 months old and still not house broken, sigh, sometimes she is good and does not poop or pee if i leave her for 5 or 6 hours, sometimes if i leave her for an hour she poops and/or pees.....it's really frustrating, but more than that i feel like a failure, i would think that she should be completely house broken by now, i don't want to crate her again but it might come to that.....any help/advice would be greatly appreciated, thank you......
